The deliberate and precise modification of the host genome using engineered nucleases represents a groundbreaking advancement in modern medicine. Several clinical trials employing these approaches to address metabolic liver disorders have been initiated, with recent remarkable outcomes observed in patients with transthyretin amyloidosis, highlighting the potential of these therapies. Recent technological improvements, particularly CRISPR Cas9-based technology, have revolutionized gene editing, enabling in vivo modification of the cellular genome for therapeutic purposes. These modifications include gene supplementation, correction, or silencing, offering a wide range of therapeutic possibilities. Moving forward, we anticipate witnessing the unfolding therapeutic potential of these strategies in the coming years. The aim of our review is to summarize preclinical data on gene editing in animal models of inherited liver diseases and the clinical data obtained thus far, emphasizing both therapeutic efficacy and potential limitations of these medical interventions.

The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 system has revolutionized targeted mutagenesis, but screening for mutations in large sample pools can be time-consuming and costly. We present an efficient and cost-effective polymerase chain reaction (PCR)-based strategy for identifying edited mutants in the T generation. Unlike previous methods, our approach addresses the challenges of large progeny populations by using T generation sequencing results for genotype prediction.

Flax is an important crop used for oil and fiber production. Although genetic engineering has been possible in flax, it is not commonly used to produce cultivars. However, the use of genome editing technology, which can produce site-specific mutations without introducing foreign genes, may be a valuable tool for creating elite cultivars that can be easily cultivated.

CRISPR-Cas9 gene editing technology, as an innovative biomedical tool, holds significant potential in the prevention and treatment of atherosclerosis. By precisely editing key genes such as PCSK9, CRISPR-Cas9 offers the possibility of long-term regulation of low-density lipoprotein cholesterol (LDL-C), which may reduce the risk of cardiovascular diseases. Early clinical studies of gene editing therapies like VERVE-101 have yielded encouraging results, highlighting both the feasibility and potential efficacy of this technology.

Accurate identification and quantification of 5-hydroxymethylcytosine (5hmC) can help elucidate its function in gene expression and disease pathogenesis. Current 5hmC analysis methods still present challenges, especially for clinical applications, such as having a risk of false-positive results and a lack of sufficient sensitivity. Herein, a 5hmC quantification method for fragment-specific DNA sequences with extreme specificity, high sensitivity, and clinical applicability was established using a quantitative real-time PCR (qPCR)-based workflow through the combination of enzymatic digestion and biological deamination strategy (EDD-5hmC assay).

This review discusses multiple aspects of follicular lymphoma (FL), including etiology, treatment challenges, and future perspectives. First, we delve into the etiology of FL, which involves a variety of pathogenic mechanisms such as gene mutations, chromosomal abnormalities, immune escape, immune system dysregulation, familial inheritance, and environmental factors. These mechanisms provide the context for understanding the diversity and complexity of FL.
